The Super Anchor Max Kit Hinged Anchor delivers 5,000 lbs minimum breaking strength in a reusable design that handles roof pitches up to 20/12 with screws or 12/12 with nails. This isn’t another disposable anchor that contractors leave behind after every job. The hinged design adjusts from flat deck positioning to steep pitch angles, while dual fastener hole sizes (7/32” and 5/16”) give flexibility for different installation requirements.
For Montana contractors working steep mountain cabin roofs or dealing with ice-damaged decking that needs frequent access, a reusable anchor that moves between jobs makes economic sense. The 11-gauge steel construction comes in either zinc-coated or Dacromet-coated options — that Dacromet coating matters when you’re dealing with Montana’s freeze-thaw cycles and spring moisture.
Load Ratings and Compliance Standards
The anchor carries a 5,000 lbs minimum breaking/average tensile strength rating with hardware proof tested to 3,600 lbs. Maximum user weight tops out at 310 lbs including tools and equipment — that’s a 250-pound contractor with a 60-pound load of shingles or tools.
| Specification | Value |
|---|---|
| Breaking Strength | 5,000 lbs (minimum/average tensile) |
| Hardware Proof Test | 3,600 lbs |
| Maximum User Weight | 310 lbs (including tools) |
| Anchor Weight | 3.0-3.5 lbs |
| Material | 11-gauge steel |
The anchor meets OSHA 1926.502, OSHA 1910.66, ANSI Z359.1-07, and ANSI A10.32-2012 standards. Super Anchor maintains third-party engineer certification through independent testing labs, not just in-house testing. That distinction matters for contractors submitting safety plans to general contractors or insurance companies.
Installation Flexibility and Kit Components
The anchor handles slopes up to 20/12 pitch with screws or 12/12 pitch with nails, and can lay flat on the deck for low-slope applications. Works on OSB or plywood decking 7/16” or greater thickness — standard sheathing on any Montana roof built to code.
Two fastener hole sizes (7/32” and 5/16”) accommodate different screw diameters, though you can’t mix fastener types on a single anchor — use either a full-nail pattern or full-screw pattern. The kit includes 3” Duplex 16d nails or accepts approved 3” wood screws.
The 3001 series Max Kit transforms the basic anchor into a complete fall arrest system:
- 5-point full-body harness with high-visibility webbing
- 5/8” diameter 3-strand vertical lifeline in 25’ or 50’ lengths
- Max-Force energy absorber with rope grab
- Hinge-2 roof anchor plus a 48” tie-off strap for dual anchor points
- Heavy-duty storage bucket
- 20-page instruction manual
That “kit in a bucket” approach means everything stores and transports together. No hunting through the truck for missing components when OSHA shows up.
The reusable design sets it apart from single-use disposable strap anchors that contractors abandon on every roof. The adjustable hinge allows use on steep pitches where fixed-angle anchors cannot work. For roofing crews hitting multiple jobs per week, the math on reusable equipment adds up fast.
Installation requires mounting directly over structural members like rafters or trusses, positioning high above the work area to minimize swing-fall risks. After any fall event or visible damage, remove the anchor from service. Fill fastener holes and restore roofing material after removal.
The system accepts vertical lifelines (5/8”), self-retracting lifelines (SRLs), and standard lanyards, giving crews flexibility to use their existing fall protection gear rather than buying into a proprietary system.
Super Anchor backs the product with a 1-year warranty from installation or first use, limited to replacement for defects in materials or workmanship. Standard warranty terms, nothing exceptional.
Frequently Asked Questions
Q: Can I use both nails and screws on the same anchor? No. Install using either a full-nail pattern or a full-screw pattern — do not mix fastener types on a single anchor.
Q: What roof pitches can this anchor handle? Up to 20/12 pitch with screws or 12/12 pitch with nails. The anchor can also lay flat on the deck for low-slope roofs.
Q: How much weight can the anchor support? The anchor has a 5,000 lbs minimum breaking/average tensile strength with hardware proof tested to 3,600 lbs. Maximum user weight is 310 lbs including tools and equipment.
Q: What’s the minimum deck thickness required? OSB or plywood thickness of 7/16” or greater — standard sheathing meets this requirement.
Q: Can I leave the anchor installed permanently? The anchor must be removed after any fall event or if visible damage is detected. Fill fastener holes and restore roofing material after removal. This is designed as a reusable temporary anchor, not a permanent installation.
